Diffusion screen lights behind1/2/2024 ![]() Surface micro-structure UV coated diffusion film is that coating a UV photosensitive material in PET film, which is embossed by the microstructure of the steel wheel (structural wheel), and the microstructure is transferred into the photosensitive material, and then it is hardened by UV. The coating material contains a solvent which could easily make the coating layer uneven because of their different evaporation there is a problem in dealing solvent exhaust dealing it is a long time and energy-consuming process for drying solvent it a poor adhesive for scattering particles, solvent and resin it is very difficult to control the uniform of the particles. ![]() The advantage is that it is a mature and widely accepted technology and the acrylic resin is easily available. The scattering particle web coated diffusion film is composed of the diffusion particles which could be inorganic particles or synthetic polymer particles and binder (acrylic resin), and the diffusion layer must be dried and hardened by high temperature. The substrate usually is a transparent optical grade PET film which has specifications of 5, 38, 50, 75, 100, 125, 150, 188 um. There are some special diffusion films that have a diffusion layer and an adhesive layer at the bottom. And coated diffusion film which has a higher light transmittance and a wider haze adjustment range is the first choice of the high-class backlight unit, and it can be divided into scattering particle web coated diffusion film and surface micro-structure UV coated diffusion film.Īs for the structure of diffusion film, from top to bottom, diffusion layer – substrate – isolation layer. The Production Process of Diffusion Filmĭiffusion film can be divided into coated diffusion film and non-coated diffusion film according to production methods. Do not position the work station with the light fixture directly behind. But we should know that it is essential in the backlight unit. What are other OSH Answer documents about lighting. Diffusion film shares a small proportion of the cost of the backlight unit, compared with the light guide plate. The upper diffusion film not only can widen the viewing angle and strengthen the mildness of the light, but also can diffuse the light and protect the light guide plate. The main function of the lower diffusion film is that filter out the shadow of the lattice points of light guide plate and the shadow of light source and concentrate the light. In general, LCD screen requires two diffusion films, the upper transparent diffusion film, and the lower white diffusion film. The theory of LCD diffusion film is that making the light pass through the medium of different refractive indexes, which has been refracted, reflected and scattered, so the optical diffusion effect is made. The diffusion film is the spread material that transforms the linear light source of CCFL or the point light source of LED into a uniform surface light source in the LCD module. It comes with a computer mount and built-in frosted lenses and diffusers that shine a soft light on your face without hurting your eyes.The Theory and Function of Diffusion Film It's USB-powered and clips directly onto your phone, tablet, or laptop giving off soft, warm, adjustable light.Īnd if you spend all day and night on video conference calls, your best option is the Lume Cube Video Conferencing Lighting Kit. When you need an inexpensive light that will work just as well with your laptop as it will your phone, we like the QIAYA selfie ring light. They're dimmable, come with eight filters, and offer endless lighting options. If you want professional-grade light, we recommend the Neewer 5600K USB LED Lights. The best lighting for webcam streaming comes down to positioning, brightness options, and your budget. It's the perfect setup for casual and professional Zoom meetings, vlogging, and FaceTime chats. ![]() The ring light and wireless remote control kit from PIXEL come with a 19-inch bi-color vlogging light, filter, mounting adapters, and a wireless remote controller. A remote control helps you make minor adjustments and do it out of the line of sight. You never want to be seen fiddling with your light, trying to make adjustments while filming.
